中捷农场地处黑龙港下游,临近渤海,地势平缓,海拔2.5—5.5米。四分场总面积5万亩,耕地3.3万亩,土质为重壤质滨海潮土。据24年气象资料计算。年均降雨量632.7毫米,年内分配很不均衡,63.6％集中在七、八两个月,地下水距地面一般不过2米,雨季容易形成沥涝灾害。由于根治海河大搞了排水工程,建起泵站7座,具备较高的排水除涝能力。排水除涝,既要保证当季作物不遭受涝灾又要为以后生产创造有利条件,也
Zhongjie Farm is located in the downstream of Heilonggang, near the Bohai Sea, with gentle terrain and 2.5-5.5 meters above sea level. Quarter total area of 50,000 mu, 3.3 hectares of arable land, soil quality is heavy loam coastal Chao soil. According to 24 years of weather data calculation. The average annual rainfall is 632.7 millimeters with a very uneven distribution during the year. 63.6% of the rainfall is concentrated in seven or eight months. The groundwater is generally less than 2 meters above the ground and the flood season is prone to lead to floods and floods. Due to the radical Haihe River drainage project, build a pumping station 7, with high drainage waterlogging capacity. Drainage and waterlogging, it is necessary to ensure that the season crops are not subject to flooding but also create favorable conditions for future production, but also
